SPECIFICATION forming part of Letters Patent No. 655,594, dated August 7, 1900.

Application filed August 27, 1898. Serial No. 689,628. (No model.)

My invention relates to organs, and particularly to reed-organs; and it has for its object to improve the same in the several points hereinafter specifically set forth,wherebyim proved actions are obtained and whereby the Y construction is simplified and reduced in cost.-k

The invention consists ot the novel devices and combinations of devices hereinafter described, and defined in the claims.

The preferred form of my invention as applied to a reed-organ is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Figure 1 is a perspective view of parts of a reed-organ having myimprovements applied thereto, the said view being taken from the front of the organ and the case and many other parts of the organ being removed. Fig. 2 is a detail in right side elevation of certain of the parts shown in Fig. 1. Fig. 3 is a perspective view of the parts shown in Fig. 1`

looking at the rear of the same. Fig. 4 is a plan view of the stop-frame and the stops, certain parts being broken away. Fig. 5 is a perspective View of a portion of the parts shown in Fig. 4, the same being shown as sectioned on the line :t5 ots of said Fig. 4 and some parts being broken away. Fig. 6 is a transverse section taken on the line 036 x6 ot' Fig. 4. Fig. 7 is a detail view in perspective, showing one of the detachable connections employed in the device. Fig. 8 is a plan View of one part ot the connection shown in Fig. 7, and Fig. 9 is a detail view in perspective of an end section of one of the iiexible stop-cords. A

In the drawingsthe keyboard of the organ is shown as exceedinglylimited in range; but this will sutiice as well for the purposes of this case as would the illustration of a complete keyboard.

In the illustration given, 1 indicates a base portion on which the parallel end plates 2 are vertically supported. The rectangular stoptrame 3 extends transversely across the end plates 2 and is rigidly secured to the upper rear portions of the same.

4 indicates the keys of the keyboard,which keys are mounted and operate in the ordinary manner.

5 and G indicate the swell-shutters, which in this arrangement may be designated, respectivel y, as the first and second swellshutters. As is usual, these swell-shutters are hinged, as shown at 7 and 8, respectively.

9, l0, 11, and 12 indicate the mute-valves, which are hinged at 13. More specifically stated, the valves S) and lO are respectively the front treble and bass mute-vaives, and the valves 11 and l2 are likewise the rear treble and bass mute-valves. The ends of these valves project through suitable passages iny the end plates 2 and are operated upon by actuating connections constructed in accordance with my invention and to be hereinafter described.

14 and 15 indicate, respectively, the operating-leaves of the treble and bass octave couplers, the same, as shown, being hinged at- 16.

The parts so far described in detail are the ordinary reedorgan construction, the functions of which are well understood, and hence for the purposes of this case need not be further illustrated.

In the ordinary organ construction the stops when moved into operative positions are extended outward over the keys, so that in striking certain chords they are very liable to be struck by the fingers and accidentally thrown back into inoperative position. In my improved construction, wherein the stops are mounted for rotary motion, it is not necessary to pull the same out over the keys when they are rendered operative, and hence the difticulty above noted is obviated. @indicates a series of these stops, as shown, eight in number, which are mounted for rotary but iXed against endwise movements in the stop-frame 3. All of these stops except the extreme lefthand member, with respect to Fig. 1, are provided With removable end disks or caps a', having crank or eccentric pins a2, and said IOO left-hand member is provided with a plane disk or cap a3. The stops a are limited in their movements toward their normal positions, as shown, by means of pins C01 and a5, respectively, on said stops a and the stopframe 3, and it will be noted that the four right-hand and the four left-hand stops are adapted to be turned in opposite directions. The connections between these stops and the mutes or other devices which t-hey control will be described after having described the knee-swel1 devices.

For the purposes of this case the device which simultaneously operates the treble and bass mute-valves and the treble and bass octave couplers will be termed the primary knee-swell and the device which under the action of the knee simultaneously opens both swell-shutters will be termed the secondary or double-forte knee-swell.

The primary knee-swell consists of a pair of rock-shafts Z) and ZY, mounted in suitable bearings h2 and b3, respectively, at the righthand and left-hand ends of the base l, anda connecting rod or link Zit, which is provided with a dependent knee-piece Zf and is connected at its ends to depending crank portions or arms Zi and (17 of said rock-shafts Z) and Zi, respectively. rlhe rock-shaft Z9 is provided with offset portions Zig, which engage the under and free edges cf the treble mute-valves 9 and ll, and between said offset portions Zig or at some other suitable point said rock-shaft Z) is provided with a third offset portion Zr.

Zim indicates a transversely-extended rock shaft or rod which is suitably mounted in the framework of the device and is provided at its inner end with a laterally-bent finger portion Z)11, which underlies the free edge of the leaf le of the treble-octave coupler. At its outer end the rock-shaft Z210 is provided with an arm or extension Z312, which, as shown, is bent to form an eye B13 and is then projected on downward and forward to form a lifting-finger Z214.

D15 indicates a plunger which is mounted for vertical movement in suitable keepers or guides, as shown, in the form of eyes 016, secured to the right-hand end plate 2. rlhe lower end of this plunger ZJ15 rests upon the offset projection Z1 of the rock-shaft b, and the lifting projection L11 of the rock-shaft Z210 rests upon the upper end of said plunger ZW.

The rock-shaft ZJ at the left-hand side of the organ, as viewed in Fig. l., and at the right-hand side, as viewed in Fig. 3, is provided with a pair of offset or projecting portions ZJ17, which engage one under each of the mute-valves l0 and l2 and when raised open said valves. At its intermediate portion this rock-shaft ZJ is provided with an inwardlyprojecting arm Zis.

b1`1 indicates a transverselyextended rockshaft or rod similar to the rock-shaft U0 and provided with a laterally-turned finger D20, which underlies the free edge of the leaf l5 of the bass-octave coupler. This rock-shaft the connecting-rod b1 is forced toward the A left, with respect to Fig. l, by pressing the knee against the depending projection b5 or, preferably, against an ordinary-hinged kneepiece (not shown) having contact with said projection h5 the rock-shafts Z) and Z/ will be simultaneously rocked and all four of the mute-valves will thereby be simultaneously opened and both of the octave-couplers will be simultaneously operated.

The secondary or double forte kneeswell comprises in its preferred form a longitudinallyfextended rock-suaft c, mounted in suitable bearings c on the right-hand end of the support l, and a transveisely-movablykneerod c2, mounted in a bearing c3 on said base l, and provided with an upturned arm c", that is pivoted to an arm or crank portion ol said rock-shaft c. The downturned end c6 of the knee-rod c2 is adapted to be directly engaged by the right knee of the operator, but would preferably be directly engaged by anordinaryhingedknee-piece. (Notshown.) Near its forward end the rock-shaft c is provided with au inwardly-extended arm or lifting projection c7, that underlies the free edge of the forward forte-valve or swell-shutter (5, and at its rear end said rock-shaft is provided with a lifting-arm es, that underlies the free edge of the rear forte-valve or swellshutter 5. For an important purpose, to be hereinafter noted, the lifting-arm es is provided with a projection or eye e9. lt is of course obvious that when the knee-rod c2 is forced toward the right, with reference to Fig. l, the rock-shaft c will be rocked and both vforte-valves 5 and G will thereby be si multaneously opened.

The eight stops shown have marked on their heads or forward ends, successively, from left toward the right, with reference to Fig. l, the following abbreviations, to wit: Geht, indicating octave; Diap., indicating diapason; Prin., indicating principal; lst f., first forte; 2nd l, indicating second forte; if, indicating double forte; liano7 and Melo., indicating melodia. These stops will be hereinafter referred to by the use of their abbreviations. The craukpin a2 of the Diap7 stop is connected by a cord or flexible connectionf with a projecting arm j" of a roekshaftj, mounted in suitable bearings f5 and provided with an offset or projected arm f1, which underlies the rear bass-reed mutevalve 12.

member of the bass-reed mute-valves will be opened Wide.' The crank-pin c2 ofthe Prim stop is connected by a cord or flexible connection g to an arm g of a short transverse rock-shaft g2, mounted in suitable bearings g3, and provided at its outer end with an arm g4, having the hooked end. The hooked end of this arm gAl is connected by a coupling clip or piece g5 and cord or flexible connection gG to an arm g7 of a rock-shaft g8, thatis mounted in one of the bearings f3 and in a bearing g, and is provided at its intermediate portion with a projecting arm or offset portion glo, which underlies the free edge of the forward bass-reed mute-valve 10. Hence when this stop is moved by rotating the same the forward bass-reed 1n utc-valve lO will be opened..

The crank-pina2 of the lst f. stop is connected by a flexible connection or cord h to the free edge of the rear forte-valve or swellshutter 5, the same as shown being directly connected to an eye h on said valve or shutter. Obviously the rotary movement of this stop will open the rear forte-valve or swellshutter. The crank-pin a? of the 2nd f.7 stop is connected by a cord or flexible connection 7n to an arm k of a rock-shaft k2, which extends from front to rear of the framework slsiown and is mounted in suitable bearings t vided with another crank or arm 7a4, which'is connected by a cord or flexible connection h5 to the free edge of the forward or frontswellshutter 6, the connection to said shutter, as shown, being made directly to an eye 706 on said shutter. It of course follows from these connections j ust described that when this latter-noted stop is turned the forward or front swell-shutters 6 will be opened. The doubleforte stop is provided with a connection whereby its movement will simultaneously open both of the forte-valves or swell-shutters. In the specific arrangement shown this result is accomplished by connecting the crank-pin a2 of the ff. stop by means of a cord or fiexible connection n to an arm n/ of a short transverse rock-shaft n2, mounted in suitable bearings n3 n4 and provided at its outer end with an arm n, having a hooked end that is in turn connected to the projection o9 on the arm cS ofthe rock-shaft c by means of a cord or dexible connection n and a clip nl. Of course with these connections the partial rotation of the if stop will rock the rock-shaft c and simultaneously open both of the swell-shutters. The crank-pin c2 of the Piano stop is connected by a cord or flexible connection p to an arm p of a short rock-shaft p2, suitably mounted in the bearing n3 and another bearingps, and provided at its outer end with an arm p4, having a hooked free end. This free end of the arm p1 is connected by a cord or Iiexible connection p5 and clip p to the free end of a pin or projection p7, which rises from the forward member 9 of the treblereed mute-valves. These connections are such At its forward end this shaft 7a2 is pro` that when the Piano stop is turned the said valve 9 will be opened. The crank-pin a2 of the Meld stop is connected byacord or flexible connection r to an arm r of another short rock-shaft r2, which is suitably mounted in the bearing n3 and in a bearing r3, and is provided at its outer end with an arm r4, the free end of which is hooked. In like manner to the arm p4 the free end of this arm r4 is connected to the free end of a pin or projection 115 on the free edge of the rear member l1 of the treble-reed mute-valves by means of a cord r6 and clip of. Again, it is evident that the partial rotation of this latternoted stop will open said mute-valve 1l.

The Octv. stop has clamped toits intermediate portion a divided spring-arm t, the prongs of which, as shown, tightly clamp a leather block t under the action of a screw t2, and, as shown, the saidlarm t is prevented from slipping on said stop by a key t3. The block t Works on the crank portion t4 of a transversely-extended rock-shaft t5, suitably mounted in one end plate 2 and in a bearing t6, and-provided at its outer end with an arm t7, that is hooked at its free end. This free end of the arm t7 is connected by a cord or flexible connection t8 and clip t9 to the previously-noted eye Z922 of the arm b21 of the shaft h2o, which operates the bass-octave coupler, as previously noted. Now it is evident that when this last-described stop is partially rotated it will through the connections just noted open up or put in operation the bass coupler. Attention is here called to the fact that the movement of this Octv. stop will not actuate the rock-shaft b of the primary knee-swell, and, on the other hand, that the operation of the primary knee-swell Will not act upon the rock-shaft t5 and arm il. When this arm t7 is turned into its operative position, it will depend straight downward and will engage the crank portion i4 of the shaft t5 approximately at a perpendicular thereto, and it will thus be frictionally held where set. Another key, such as any of those above described, may be provided with connections to a cord o, or this cord c may be connected to one of the keys and connections already shown. In either case the trebleoctave coupler could be operated by a stop. In connection with one or any number of the stops l provide a device or devices for frictionally holding said stop or stops at any intermediate point or points between their extreme movements. The purpose of such construction is to enable the stop to. be set so that it will have variable actions on the valves or mechanismswhich it controls. As

In Figs. 7 and 8 the exact relation of the clip t9 to the hook end ot the arm tl is illustrated, and by reference to these figures it will be noted that said clip 't9 has a perforation 1510, through which the hooked end of said arm t7 is adapted to be passed, and is also provided with a notch t, adapted to embrace 'the body of said arm while the clip is being placed in working position. struction is shown as applied to the other clips; but it will not be necessary to further note the same.

In Fig. 9 one of the detachable looped ends of the connections to the crank-pins (t2 of the This may be assumed l to be the upper end ofthe cord or connection K h, and it may be noted that the loop is formed by connecting the downturned end of said cord to the body portion thereof by means -of stops is illustrated.

For example,.the so-called springarm used in connection with the bass-octave coupler might be applied to any other of the stops, or, vice versa, any of the other forms of connection might be applied to this particu- This spring-arm construction has the advantage that it may be very readily apy lar stop.

plied tothe sliding stops of organs now in rotary stops. I-Iowever, the crank attachments may also be quite easily applied in the same Way and for the same purpose. As previously indicated, the friction device for holding the stops in intermediate set positions may also be applied to any or all of the stops. Furthermore, as previously indicated, any desired number of additional stops provided with any of the connections above described may be provided. The spring-arm t being split or divided adapts it for application to the stops of an ordinary organ, thereby making it possible to very readily convert the sliding stops into rotary stops.

It will of course be understood that alterations in the details of construction above set The same specific con-` forth may be made within the scope of my invention. For example, the rotary stops might be given complete rotations instead of partial rotations, as illustrated. Again, the construction herein described while having a particular relation to reed-organ construction may in many cases be applied to pipeorgan constructions.

Having now described myinvention, what I claim, and desire to secure by Letters Patent of the United States, is as follows:

l. In an organ,the combination with a kneeswell involving a rock-shaft having a projection connected to one of the sound-actuating devices, by a cord or ilexible connection, of a rotary stop operating on said sound-controlling device through a llexible connection, whereby the actions of said stop and kneeswell do not interfere one with the other.

2. In an organ, the combination with a rotary stop connected to the sound-controlling mechanism actuated thereby, of a t'rictionbrake applied to said stop for vfrictionally It is obvious that the several specifically-3 different connections between the variousf stops and the valves or other devices whichf they operate may be substituted or interchanged in constructing or rearranging or-'` holding the same in various intermediate positions, which brake consists of asplit springclamp, means forsecuring said clamp against rotation, and means for variably drawing said clamp onto said stop to put the same under slipping friction, to move in either direction, substantially as described.

3. In an organ, the combination with one of the stops and sound-controlling mechanism actuated thereby, of connections between the same involving the hooked arm t7, the flexible connection and the clip t secured to said flexible connection, and having the peruse to convert the same into an organ having foration tw and notch t engageable with said hooked end, substantially as described.

4. In a reed-organ, a finger-operated stop having suitable connections to the sound-controlling meehanism operated thereby, in combination with a friction-brake applied to said stop, which friction-brake is adapted to be set for a predetermined tension and when set to frictionally hold said stop against Inovement, in either direction, substantially as described.

In testimony whereof I attix my signature in presence of two witnesses.
